It is hardly necessary, in speaking of the Whales, to direct attention to their monstrously-developed osseous system and large fleshy tongue, as also to their correspondence with Fishes in the entire form, manner of living, and imperfect nose. Their head is still confluent with the neck, the teeth are horny plates of coalesced hairs, or uniform simple points, as in Fishes. Most of them have even dorsal fins; the two udders are hardly separated from the sexual parts.
Fam. 11. Reptilian Thricozoa, Pigs.
Four feet with hoofs; canines and mostly also incisors; stomach simple, do not ruminate—Nylghau, Pig, Elephant, Rhinoceros, Horse. These animals love the marshes, and are through their mode of living, as also their form, similar to the larger Reptiles; or, in other words, through their colossal skeleton, with preponderating muscular mass, they are Myozoa, through the proboscis or snout, Rhinozoa.
Fam. 12. Ornithic Thricozoa, Ruminants.
Toes bifid, surrounded by a hoof; above there are rarely incisor and canine teeth; udders behind; stomach fourfold; they ruminate. The horn-formation indicates a relationship with feathers; the want of incisor teeth, large ears, and timidity of disposition that of the family with the class of Birds.
Both families enter into connexion with the Whales through the size of their body, the structure of their feet, form of the head and disposition towards water and mud. They are quadrupedal Whales, which have come out of the water, and adopted a manner of living like the Amphibious Reptiles and Grallatorial Birds.
Order 5. Æsthesio-Thricozoa—Unguiculata.
3571. Here for the first time an equiponderance of the sensorial organs makes its appearance and along with it therefore a resemblance between the animals, which is no more interrupted by such strange or odd forms, as in the preceding orders.
All of them have divided toes with claws or nails, and all kinds of teeth with multiacuminate enamelled molars.
3572. No doubt can exist about the animals belonging to the present order; they are the Apes, Bears, and Carnivora generally, as Seals, Cats, Dogs, Martens, and such like beasts.
